The filling rate of the first tank is this: 
The filling rate of the second tank is this:
Add them to get the combined rate:
Make a common denominator by multiplying the first fraction by 2/2:
Adding them together, we get:
So, now we know that the combined rate is 3 tanks per 2 hours... but we need to know how long it will take to fill only one tank. So, we need to find the unit value, which we do by doing this:
Then we can cross-multiply:
And divide both sides by 3 to get our final answer:
So, it takes 2/3 of an hour, or 40 minutes.
Hope I helped, let me know if you have any questions :)

Step-by-step explanation:
The first thing that you have to do is take the roots that you're given and write binomial products.
Remember that a root is the value of "x" in a binomial expression, so the binomial expression itself will have the opposite sign of the root.
The next thing you have to do is multiply the roots together. A good way to do this is the "box method."
(See attachment below for the multiplication of and
. )
Next, multiply your new trinomial by your remaining binomial. (See additional attachment below for the multiplication of and
)
The resulting polynomial is .
